- IMPRQVEMENT IN AIR-GUNS.

Specification forming part of Letters Patent No. 173,540, dated February15, 1876; application filed August 11, 1875.

To all whom it may concern:

Be it known that I, WILHELM HEBLER, of New York city, in the county andState of New York, have invented a new and Improved Air-Gun, of whichthe following is a specification:

In the accompanying drawing, Figure 1 represents a side view of myimproved air-gun; Fig. 2, a vertical longitudinal section of the same,with parts cut off. Figs. 3, 4, 5, and 6 are vertical transversesections on the lines c 0, 70 7a, a: x, and y y of Fig. 2, respectively.

Fig. 7 is a detail horizontal section on line y y of Fig. 4 of the lockmechanism; and Fig. 8 is a detail side view of the lock mechanism.

Similar letters of reference indicate correspondii g parts.

The object of my invention is to furnish for the use of sportsmen andlovers of targetshooting an improved air-gun, designed to reach therange of an ordinary rifle.

My invention consists in a novel combination and arrangement of valvesand other devices, in connection with the air-compressing chamber, ashereinafter described.

In the drawing,'A represents the stock of the air-gun; B, theair-compressing chamber; (J, the barrel; D. the air-cylinder, and E theramrod. The barrel 0, aircylinder, and rod are arranged in front of theair-chamber B vertically, one below the other, as shown in the drawing.The air-cylinder D guides the piston F,- with piston-rod F which isoperated by rotary levers G G and crank H, having handle I. The barrel 0is. provided with sights, which are adjustable for the distance desired,and are also corresponding with the rotations of the crank and thedegree of compression of the air in the air-chamber.

If a large amount. of air be forced into the air-chamber, the expansiveforce of the air will drive ,the ball or shot as far as any other rifle.

The air-chamber B consists of a wider part,

a, and a narrower part, I), which extends backinto the stock. It is madeof sufficient strength for the pressure of the compressed air therein,and screwed or otherwise firmly connected to the partition or socket d,which is perforated by channels 6 e, which connect the air-cham- .berwith the air -cylinder D and barrel 0.

These channels a c are closed by two conical valves, ff, of leather orother suitable material, which 'are secured by collars g g on pins orshafts h h. These shafts h h are guided by the perforated arms ofsupport or standard L, which is screwed to socket d. Spiral springs z tare placed between standards L and collars g g, and press the valves ffagainst the channel-openings, closing them accurately and tightly. Thevalve f of the barrel-channel e is placed sidewise of valvefi-so thatthe channel 6 extends obliquely through socket d, to connect with barrel0. The shaft h of valve f extends through the socket d, and projectsbeyond it, to be operated upon by the lock mechanism on discharging thegun. The ball or shot is set into the barrel 0 by the ramrod E in theusual manner. The air-cylinder D has an opening, I, through which theair enters on the upward stroke of piston F as the same passes beyondit. The

downward stroke compresses the air, and forces the same, on the recedingof valve f, in to air-chamber B. The piston F is made of a series'oflayers, m, of leather or other packing, firmly wedged between theshoulders n. The PlSlZOH-IOd F has a tubular extension, F to the head 0of which is suitably pivoted the lever g. The projecting part of headoslides in slot 0 of air-cylinder. The shorter lever G is pivoted at pto the lower side of air cylinder D. To its end are connected lever Gand crank H, so that by the rotation of the latter the strokes of thepiston are produced, and the air accordingly forced into the airchalnberB. The lock mechanism is secured sidewardly to projecting lugs r of theair-cylinder D, which carry the lock-bolt M. A short handle, q, of boltM, projects. sidewise, and serves to press the same-forward till ahookshaped arm, 8, of trigger t, which is suitably acted upon by spring8, looks over a lug, 1", of the broad head t of bolt M. The bolt Mpasses, by means of slot m, over pivot m of trigger t. Spiral springs uand u are placed between handle q and lug r and lug 1" and the shoulderu on bolt M, so that on the release of the trigger-arm the bolt M ispressed forward by the stronger spring to till it strikes the valve-pinor shaft h','being then instantly withdrawn again by the second springa. The valve f is therefore momentarily disconnected from channel 0,and, by the action of the air, the bail discharged. The air-chamber isthen charged again with compressed air by the turning of thecranklevers, snot-her hall insorted, and the trigger set, whichoperations are attended to easily and quickly, as no parts need to beseparated.

The lock mechanism is protected by a casing, N, which is slotted forlever q.

As the lock mechanism will be patented separately, no claim is here madeto it. 7

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

8. In combination with air-chamber B, the

,valvesff, having collars g g and springs M,

as described. WILHELM HEBLER.
